Convection is transfer of energy through movement of liquid particles. Let us take some steps back and revise a number of principles. First of all, you should remember the concept of density. If two parts...

Impulse is Force x TimeThe force has been given as 180N. The time that the foot was in contact with the ball was 0.05sImpulse=FxtImpulse=180x0.05Impulse= 9Ns

The Loop rule, this states that the sum of the potentials in a loop must be equal to 0.The Junction rule, this states that the sum of the current entering the junction must be equal to the sum of the curr...

The plum pudding model defined the atom as a particle in which the charge and the mass of the atom was spread evenly. An experiment was set up in which alpha particles where shot to a thin gold foil. The ...
